Which of the following are star-like objects that contain less than 0.08 solar masses and will never raise their core temperatures high enough that the proton-proton chain can begin?
A)brown dwarfs
B)Herbig-Haro objects
C)Bok globules
D)T Tauri stars

Question

Quizplus · Accepted Answer

Brown dwarfs are star-like objects that are too small to sustain nuclear fusion in their cores, preventing them from becoming fully-fledged stars. They contain less than 0.08 solar masses and thus are unable to raise their core temperature high enough to ignite nuclear fusion through the proton-proton chain. The other choices listed (B) Herbig-Haro objects, (C) Bok globules, and (D) T Tauri stars are objects associated with star formation and are not brown dwarfs.
